Dual sided nonwoven articles for cleaning

Abstract

The present invention relates to a dual performance cleaning article, wherein said article is comprised of a first abrasive meltblown surface that facilitates the process of loosening particulates, such as dust and dirt, and an opposing second soft, air permeable surface, which is capable of absorbing and/or picking up particulates and liquids. The meltblown layer comprises coarse discontinuous filamentary elements, formed from adjusting the variable commonly utilized in the traditional meltblown method.

What is claimed is:  
     
         1 . A method of making a nonwoven dual sided home care cleaning article comprising the steps of: 
 a. providing a nonwoven fabric comprised of continuous bonded regions and at least two or more distinct pillow regions, wherein said nonwoven fabric comprises an air permeable precursor web and a meltblown precursor web comprising filaments in the range of 5-50 microns that are thermally bonded to form said cleaning article; said bonding regions define at least two or more distinct pillow regions comprising layers that are essentially free of any integration; and    b. a cleansing composition comprising an effective amount of a cleansing surfactant, said aqueous liquid cleansing composition being coated onto and/or impregnated into said substrate to the extent of from 50% to 500% by weight of the substrate.    
     
     
         2 . A method of making a nonwoven dual sided home care cleaning article as in  claim 1 , wherein said cleansing composition is an aqueous or non-aqueous composition.  
     
     
         3 . A method of making a nonwoven dual sided home care cleaning article as in  claim 1 , wherein said cleansing composition is selected from the group consisting of alkylpolysaccharides, alkyl ethoxylates, alkyl sulfonates, organic solvents, mono- or polycarboxylic acids, odor control agents, peroxides, hydrogen peroxides, thickening polymers, aqueous solvent systems, suds suppressors, perfumes or fragrances, detergent adjuvants, buffers, preservatives, antibacterial agents, colorants, bleaching agents, abrasive compounds, degreasers, chelants, enzymes, hydrotropes, and the combinations thereof.  
     
     
         4 . A method of making a nonwoven dual sided personal care cleaning article comprising the steps of: 
 a. providing a nonwoven fabric comprised of continuous bonded regions and at least two or more distinct pillow regions, wherein said nonwoven fabric comprises an air permeable precursor web and a meltblown precursor web comprising filaments in the range of 5-50 microns that are thermally bonded to form said cleaning article; said bonding regions define at least two or more distinct pillow regions comprising layers that are essentially free of any integration; and    b. a cleansing composition comprising an effective amount of a cleansing surfactant, said aqueous liquid cleansing composition being coated onto and/or impregnated into said substrate to the extent of from 50% to 500% by weight of the substrate.    
     
     
         5 . A method of making a nonwoven dual sided personal care cleaning article as in  claim 4 , wherein said cleansing composition is an aqueous or non-aqueous composition.  
     
     
         6 . A method of making a nonwoven dual sided personal care cleaning article as in  claim 4 , wherein said cleansing composition is selected from the group consisting of abrasives, anti-acne agents, anticaking agents, antioxidants, binders, biological additives, bulking agents, chelating agents, chemical additives, natural additives, colorants, vitamins, cosmetic astringents, cosmetic biocides, denaturants, drug astringents, emulsifiers, external analgesics, film formers, fragrance components, humectants, emollients, opacifying agents, plasticizers, preservatives, propellants, reducing agents, skin bleaching agents, skin-conditioning agents, skin protectants, solvents, foam boosters, hydrotropes, solubilizing agents, suspending agents, sunscreen agents, ultraviolet light absorbers, viscosity increasing agents, and the combinations thereof.  
     
     
         7 . A method of making a nonwoven dual sided industrial cleaning article comprising the steps of: 
 a. providing a nonwoven fabric comprised of continuous bonded regions and at least two or more distinct pillow regions, wherein said nonwoven fabric comprises an air permeable precursor web and a meltblown precursor web comprising filaments in the range of 5-50 microns that are thermally bonded to form said cleaning article; said bonding regions define at least two or more distinct pillow regions comprising layers that are essentially free of any integration; and    b. a cleansing composition comprising an effective amount of a cleansing surfactant, said aqueous liquid cleansing composition being coated onto or impregnated into said substrate to the extent of from 50% to 500% by weight of the substrate.    
     
     
         8 . A method of making a nonwoven dual sided industrial cleaning article as in  claim 7 , wherein said cleansing composition is an aqueous or non-aqueous composition.  
     
     
         9 . A method of making a nonwoven dual sided industrial cleaning article as in  claim 7 , wherein said cleansing composition is a solvent selected from the group consisting of oils, paraffinic solvents, polybutylenes, polyisobutylenes, polyalphaolefins, toluenes, sequestering agents, corrosion inhibitors, abrasives, petroleum distillates, and the combinations thereof.  
     
     
         10 . A method of making a nonwoven dual sided medical cleaning article comprising the steps of: 
 a. providing a nonwoven fabric comprised of continuous bonded regions and at least two or more distinct pillow regions, wherein said nonwoven fabric comprises an air permeable precursor web and a meltblown precursor web comprising filaments in the range of 5-50 microns that are thermally bonded to form said cleaning article; said bonding regions define at least two or more distinct pillow regions comprising layers that are essentially free of any integration; and    b. a cleansing composition comprising an effective amount of a cleansing surfactant, said aqueous liquid cleansing composition being coated onto and/or impregnated into said substrate to the extent of from 50% to 500% by weight of the substrate.
